General Description

The Hard Cut series is recognized as the ultimate in high quality cutting oils. Hard Cuts are intended to make the hardest applications easier and more profitable by improving part quality and by reducing tooling costs. Hard Cut 521 is one of many oils in the Hard Cut Series. Hard Cut 521 is heavier in viscosity and is intended for more demanding applications. It can be recirculated in most milling and turning machines, but is heavy enough for light to medium duty forming and drawing applications.

Application

APPLICATIONS Screw Machines, large diameter bar stock or difficult to machine stock (hex, square, etc.). Metal Forming, light to medium duty stamping, forming and drawing. CNC Turning Centers and Machining Centers, call for recommendations Fine Blanking Tapping and Threading Cold Heading Broaching, vertical and horizontal Bar Feeder Lubricant, call for recommendation

Materials

Stainless Steels Alloy Steels High Temperature Alloys Aluminum, Brass and Copper Titanium Compatible with all metals

Maintenance

While straight cutting oils are not susceptible to the broad range of problems encountered with water based fluids, regular maintenance does improve their performance and extend their life. The Hard Cut oils are designed to reject foreign contaminants, such as metal fines. If the performance of the oil begins to deteriorate, remove the oil from the machine and allow settling in a drum or settling tank for 3-7 days. Fines and contaminants will settle to the bottom. After settling return the top 80% to the clean machine. In order to get the maximum life from your oil, keep the sump free of cleaners, solvents, rust inhibitors, coolants and other contaminants, which may inhibit performance.

Cleaning

All Hard Cut oils are formulated to minimize cleaning time. They are cleanable in both aqueous and solvent systems. For best results use a Hangsterfer’s Ozonic Series cleaner or recommended aqueous cleaner. Both style cleaners work best at removing Hard Cuts when heated to 140°F (60°C).
